Configuration

Contents


STK1005 use dip switches to configure de-multiplexers that connect the peripheral IO pins of AP7200 to the STK1000 interfaces on the motherboard to daughter board connector. The STK1000 documentation explain how these STK1000 interfaces are used on the motherboard.

Summary of configuration switches

flipping a switch (or in some cases two) the de-multiplexer will connect the interfaces in column 2 with the peripherals in column 3.

Default settings (as they should appear when the STK1005 is taken out of the box) should be all "Off". This will enable:

  • Booting from NOR flash
  • Ethernet
  • USART4 and SSC0
  • MMCB in 8 bit mode (MMCplus connector on STK1005)
  • USART1 (IrDA)
  • MMCA (on STK1000)
  • Audio

Power jumpers

The 10 jumpers in the bottom right corner are used for connecting power to AP7200. The jumpers used to connect power is intended to be used for current measurements and should therefor normally be populated. By removing one of these jumpers and connecting an ampere meter in series the current consumption of AP7200 can be measured.
